I installed WinOF-2 for Windows Server 2019 from this page:

https://www.mellanox.com/products/adapter-software/ethernet/windows/winof-2

Then I installed DevX SDK from C:\Program Files\Mellanox\DevX SDK
and set environment variables:

$env:DEVX_INC_PATH = "C:\Program Files\Mellanox\MLNX_WinOF2_DevX_SDK\inc"
$env:DEVX_LIB_PATH = "C:\Program Files\Mellanox\MLNX_WinOF2_DevX_SDK\lib"

Meson complained no more, but the build failed, log is below.
What am I missing? Note: I'm building the whole series.

Another question, why there's a clang restriction?
